Deck General USCG Question #4415 (Set 141)

A MODU displacing 29,500 long tons has a KG of 60 feet. A weight of 500 long tons is added at a VCG of 150 feet. What is the change in KG?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 1.5 feet upward

Adding weight above the vessel's center of gravity raises KG. Calculate final vertical moments: (29,500 LT × 60 ft) + (500 LT × 150 ft) = 1,845,000 ft-tons. Divide by final displacement (30,000 LT) to yield new KG of 61.5 feet. The upward change is 61.5 minus initial 60.0 equals 1.5 feet.
